Jack (co)authored 250 scientific publications and 72 patent applications. His team’s research on biofuels production from agricultural residues has been commercialized by DSM. In 2016, he received an ERC Advanced Grant and in 2019 he received the Stevin Price.

Prof. dr. Hermen Overkleeft – Scientific director of Leiden Institute of Chemistry
Prof. Herman Overkleeft studied chemistry at the University of Amsterdam, where he received his PhD degree in 1997 on the subject of glycosidase inhibitor design. After postdoctoral research at Leiden University on synthetic methodology and Harvard Medical School, he became Full Professor in Bioorganic Chemistry at Leiden University. Since 2017 he combines his chemical biology research on immunity and glycobiology with managing the Leiden Institute of Chemistry, as Scientific Director.



Prof. dr. ir. Mark van Loosdrecht – Professor Delft University of Technology
Prof. Mark van Loosdrecht studied Environmental Hygiene at Wageningen University. He continued working on bacterial adhesion and received his PhD in 1988. After the receiving of his PhD, he started working at the Delft University of Technology and in 1999 he became the chair professor in Environmental Biotechnology at the Delft University of Technology. He is fascinated by Microbial Ecology and how it can be applied in the design of new processes for wastewater treatment and waste-to-product processes. In 2014 he received the Spinoza Price.


Drs. Henri Lenferink – Mayor of Leiden
Henri Lenferink has been mayor of Leiden since 2003. In 1984 he received his Master of Arts in history from Radboud University Nijmegen. In 1986 he became member of the city councill of Arnhem, where he also became alderman of i.a. housing and finance. Before this period he was a member of the PvdA.





Prof. dr. Ulf Hanefeld – Professor TU Delft
Prof. Ulf Hanefeld received his PhD from the Georg-August-Universität of Göttingen in 1993. After postdoctoral years with among others Prof. J. J. Heijnen and Dr A. J. J. Straathof (both from Delft Technical University), he received a fellowship from the Royal Netherlands Academy of Arts and Sciences (KNAW). His research in Delft focuses on enzymes, in particular those that enable the formation of C-C bonds or catalyse reactions that are chemically extremely difficult to perform. Furthermore his research is about the immobilisation and application of enzymes in organic synthesis.


Prof. dr. Han de Winde – Professor Leiden University
Han de Winde obtained a MSc in organic chemistry and biochemistry at the Vrije Universiteit of Amsterdam. He obtained a PhD in molecular biology at the University of Amsterdam and was assistant professor at the Laboratory of Molecular Cell Biology, Catholic University of Leuven. Since April 2013 Han de Winde is the vice dean of the Faculty of Science, at Leiden University and Chair of Industrial Biotechnology at the Leiden Institute of Biology. His research focuses on microbial molecular genetics and metabolic engineering, specifically in the area of nutrient- and environment-induced signal transduction and control of physiology, growth and development of bacteria, yeast and fungi.

Marja van Bijsterveldt – Mayor of Delft
Marja van Bijsterveldt started her career as a nurse. She developed an interest for governance and, at a young age, became a member of the city council of Almere. After working as an alderman there, she was appointed mayor of Schipluiden. She was from 2010 to 2012 the State Secretary and the Minister of Education, Culture and Science. For a few years, she was the CEO of the Ronald McDonald Kinderfonds, the Dutch branch of the Ronald McDonald House Charities. Since 2016, she is the proud mayor of Delft.


Prof. dr. ir. Tim van der Hagen – Rector Magnificus Delft University of Technology
Prof. Dr. Ir. Tim van der Hagen studied Applied Physics at the Eindhoven University of Technology. He received his PhD at the Delft University of Technology (TU Delft) in 1989. He has been the director of the Reactor Institute Delft for seven years and has been Full Professor of Reactor Physics. Since 2018 he has been the Rector Magnificus of TU Delft. Furthermore he is chairman of the ‘Taakgroep Innovatie van het Klimaatakkoord’, which is considered with the necessary innovations for a more sustainable society.

Prof. mr. Carel Stolker – Rector Magnificus Leiden University
Carel Stolker is Rector Magnificus and President of the Executive Board of Leiden University. He is also a Professor of Private Law. Stolker started his academic career in 1979 at Leiden University. In 1988 he obtained his PhD based on a comparative law dissertation on medical liability. He has written in national and international journals on diverse private law and science philosophy topics.




Prof. dr. Marcellus Ubbink – Program director Life Science and Technology.
Prof. dr. Marcellus Ubbink studied Biology at Utrecht University. In 1994 he received his PhD cum laude at the Leiden University for his thesis ‘Cytochrome c-550 and the MADH redox chain from Thiobacillus versutus’. He studies dynamic protein-proteins and protein-ligand complexes, with a particular interest in the dynamic complexes of redox enzymes. Since 2010, he is also Full Professor in Protein Chemistry at Leiden University and since 2019 he is the program director of Life Science and Technology.
